MAX W. VOIGTMAN, OF ST. LOUIS, MISSOURI MACHINE FOB, AFFIXING IMHLTERIALTO AND EMIBELLISHING- BOOK COVERS.

Application filed September 23, 1920.

1' '0 all whom it iimy concern:

Be it known that l Mex "W. Voicruinv, a citizen of the United States ofAmerica, residing at St. .lllouis in the State of lvlissouri haveinvented a new and useful Machine "for xiug Material to and EmhellishingBool: (lovers of which the following is a speciii cation.

This invention has for its prime object the provision of a simple,compact, durable and inex iieus'iive machine comprising means forrapidly performing (he operation of t tllTI1- ing a narrow margin oflinen, canvas leather or other suitable material over upon the innersuriace of the boards forming the cover of a book, and for scoring orotl'ierwise cmbellishing the outer surface of the cover. Referring tothe accompanying drawing Figure 'l is a front elevation of the completemachine; Figure 2 a side elevation thereof taken along line 22 of Figure1 Figure 3 a detail sectional view taken along line 3-3 of Figure lFigure l a top plan view depicting the innersurface of a book-cover withthe maierial-aliixing devices in engagement therewith; Figure afragmentary detail. on enlarged scale, of the elements shown in Fig ureeq Figure 6 a side view of the frame element hereinafter described;Figure 7 a top plan view of the bed upon which the book-cover isdisposed: and Figure 3 a perspective of one of the devices employed forpressing the material at the corners of thecover when covers withrounded corners are being made.

The machine comprises a pair of stand.- ards 1 provided with guide-ways2 for the reception of guide-blocks 3- formed on tegral with plate 5which is also provided with tapered extensions 6 secured to rods 7-7 bythreaded bolts 8. Disposed beneath said plate is the bed 9 upon whichthe bookcover 10 is laid after the linen, canvas, leather or othermaterial has been aflixed to its outer surface. and by reference toFigure 3 it will be noted that said bed rests within the upturned flangell. of plate 12 and may be adjusted with respect to the upper edge ofsaid flange by insertion or withdrawal of an intermediate plate 13. Theupper edge 01 flange 11 is preferably mortised or slotted at intervalsfor the provision. of a plurality of segments M which fit within thesimilarly mortised lower edge of pressing-bars 15 as 5pci ..u=,calion ofLetters Patent.

shown (in dotted outline) in Figure 5, said segments being hingedlyconnected by the projection therethrough of a pin 16.

When books having rounded corners are to be cox cred the plate 12 thenemployed will have a corresponding form and a plurality of pressingdevices such as shown in lligure 8 will supplant flange 11 at thecorners of said plate. Said devices consist of a bracket 17 (having thesame height and thickness as said flange) secured to said plate byscrews 1.8 and slotted at l9 "for the reception of a wedge-shaped member20 hingedly supported between bracket-arms 17 by pin 21 which, when theparts are assembled, has the same location as hinge 16.

Surrounding flange 11 is a frame 23 having a plurality of pins 24depending from its under surface which project through a stationaryplate 25 affixed to standards 1 and contact with a vertically movableplate 26 having guide-blocks 2'? extending within guide-ways 2, it beingnoted by reference to Figures 1 and 3 that the hinge line 1.6 ofpressing-bars 1.5 is considerably above said rame when the latter is atrest so that said bars may be "forced upward and outward, with members20 as hereinafter described.

Secured to the under surface of bed 9 by screws 28 is a block 29 whichextends through apertures of corresponding size in plates 12- and 13 andterminates directly above cam 30 affixed to shaft 31. Said shaft issupported by adjustable bearings 32 and connected with rods 7-4 bycranks 33, rod 7 being also connected by crank 34 with stub-shaft 31which is rotated by hand-wheel 35 and supported by adjustable bearing36. Shaft 31 is further supported adjacent to cam 30 by standards 37having a convex base 38 resting upon concave blocks 39 and surmounted byhalf-bearings 40, and it will be appreciated that a shim or shims 41 maybe employed to compensate TfOl the wear of said bearings and that, byreason of the described formation of elements 38-39, said standards maybe positioned beneath said shaft after the machine has been assembled.

If it is desired to score or impress the outer surface of the cover, ashallow groove is cut in bed 9 and a steel rule 42 is laid therein asshown in Figures 5 and 7 or a die may be sunk in the bed should otherornamentation be required.

The operation of the machine is as :Eollows. Cloth, linen, leather orother material having been affixed with glue-to one side of the boardswhich are to form the cover or the book and said boards thus hingedlyconnected, the cover is then placed upon bed 9 withthe uncovered side ofsaid boards uppermost and with a narrow margin 01'? the material broughtover "the edges or" the boards. This margin is denoted in Figures 4t and5 by numeral 4L2 and may be observed upon inspection of any book havingcovered boards. The object now being to evenly and quickly secure saidmargin to the inner surface of. the boards, shaft 31 is rotated throughthe agency o'l' wheel 35 and pins 43 secured to said shaft are thusbrought against plate 26 whose upward movement against pins 24: servesto lift frame 23 upon which pressing-bars and pressing mem here areresting as shown in Figures 1 and 3. Said bars and members are thusforced inward with reference to flange 1.1 of plate 12 and press saidmargin ot the covering material. firmly against said boards as shown inFigures 4 and 5, this position being maintained until bed 9 is raised byengagement of cam with the lower ex tremity of block 29, and as the bedwith the cover thereon emerges from said flange said bars and membersare lifted and returned to the position shown in Figure 3 and the entirecover is then pressed by plate 5 which has been moved downward byrotation of cranks iii-34.

Having thus fully described the invention, what I claim as new anddesire to secure by Letters-Patent is l. A machine of the characterdescribed comprising a bed adapted to support a bookcover a platebeneath said bed having an upturned flange surrounding said bed, membershingedly connected with said flange, a tE-rame enclosing said flange,means torlifting said frame against said members to position the latteragainst said cover, and mechanism for raising said bed subsequent to theoperation of said means to position said members against said frame.

2. A machine of the character described comprising a bed adapted tosupport a bookcover, a plate beneath said bed having an upturned flangesurrounding said bed, mem bers hingedly connected with said flange, aframe enclosing said flange, means for lifting said frame against saidmembers to position the latter against said cover, mechanism for raisingsaid bed subsequent to the opera tion of said means to position saidmembers against said frame, and devices for pressing the entire coverafter removal therefrom of said members. 7 y
